CAN-LABELIN SPEUEFCATION forming part'of Letters Patent No. 445,418,dated January 27', 1891.

Application filed May 7, 1890.

To all whom zit hwy-concern:

Be it known that I, HENRY ALBERT, a citi-` zen of the United States,residing at Orescent Oity,Del Norte county, State of California, haveinvented an Improvement in Oan- Labeling Machines; and I hereby decla-rethe following to be a full, clear, and exact description of the same.

My invention relates to the class of max o chines for pasting the labelsoneans of all descriptions; and it consists in the novel features ofconstruction, arrangement, and combination hereinafter fullydescribed,and speciiically pointed out in the claims.

The object of my invention is to provide a simple and effective machineof this class.

Referring to the accompanying drawings for a more complete explanationof my invention, Figure l is aperspective view of my 2o machine. Fig. 2is a view of the paste-roller and can-puller. Fig. is a longitudinalsection of the machine. Fig. a is a side elevation of the switch. Fig. 5is a plan view showing the centering-molines. Eig. G is a crosssectionof the machine.

A is the frame of the machine7 having its upper portion formed into arunway a for the cans. lVithn this runway is adapted to be reciprocateda frame B, which carries in its rear portion the pasting-roller Gand hasattached to it the can-puller l).

The frame B has on its sides carryingrollers l), which are mounted intrack-grooves a in the sides of the runway, so that said frame may bemoved back and forth with the least amount of friction. lts movement iseffected by the following` mechanism Extending` rearwardly from it. is along vguide-stein D', the

rear end of which passes through a suitable guide-socket at the rear ofthe main frame A.

Mounted in rear standards a2 of the main frame is a shaft E,having onone end a hand- 5o crank c., as here shown, or a belt-pulley, in

. order to apply power to the device. lts other Serial No. 350,927. (Nomodel.)

end has a suitable iy-wheel. The shaft E has a long` crank c at itscenter, provided in its outer end with an anti-friction. roller c2.Mounted in the top of the standards is a rockshaft E, to which issecured a downwardlyextending and longitudinallyslotted lever f, whichreceives the antifriction roller of the crank e, said crank playing upand down in the slotted lever and thereby vibrating it 6o with itsrock-shaft F above. The lower end of this lever is connected by a linkf2 with the guide-stem of the frame B. Now by operating the shaft E theframe is reciproeated in the runway.

The particular advantage of this construction may be thus stated: Thestroke of the guide-stem b quite long, and it would take a crank with alarge sweep if connected ordinarily; but in my device I have but a com-7o paratively small sweep andthe fall and rise of lever f are veryslight. This gives a more direct pull on the stem. The pasting-roller O,which is carried in frame B, is so mounted as to be verticallyadjustable. In the sides of the frame are made grooves c, in which arethe bearing-blocks c', adapted to be moved up or down by set-screws c?.The end spindles c of the roller O extend into the grooves and rest onthe blocks. The roller can by So these means be nicely adjusted, mayaccommodate itself to the surface over which it travels, and may beremoved when required.

By making the grooves c inclined slightly, as shown, the roller can bekept hugged up close 8 5 to the feed-roll of the paste car, hereinafterdescribed. l

The can-puller consists of side plates and top bars, said bars beingseparated sufficiently to allow of the intervention of the 9o topfriction and pressure roller d, the ends of which are mounted freelyinslotted bearings tZ, so that said roller may rise and fall to providefor different-sized cans, being controlled, however, in this movement bysprings (Z2, bearing upon its ends, so that it is normally held down toplace with its lower surface projecting below the top bars and heldpositively on top of the can. The can-puller is connected with the frameB by a pivotal connecroo tion formed by rearwardly-extending arms d3,pivoted at their rear ends to the said frame,'so that the can-puller maybodily rise and fall through an arc in a vertical plane.

Upon the inner surface of the side plates of the can-puller near theirupper portion are the four small rollers el, which, when thepuller-frame is dropped down upon the can, bear on said can near eachend and roll and guide it along. Its rolling action is thereby insuredand all sliding prevented. The small rollers may be separated sufticiently to provide for dilferent diameters of cans and for anyunevenness, such. as a drop of solder. They could extend across thewhole length of the cans, but are preferably located at the end. Theyare above the caus center to insure its rolling. The top roller d iscovered with felt or other suitable material, or it may be, made ofrubber.

The operation of the machine as far as described is as follows: At itsfront end it is provided with an inclined guide-channel G, in which thecans are placed and down which they run into the forward end of therunway a. llere a suitable mechanism, to be presently described, islocated, whereby but one of the cans is allowed to be drawn forward at atime. The frame B being run forward, its can-puller comes down upon thetop of the can, the ends of which iit between the sides of the pullerand between the small rollers, while the top roller bears upon the topof the can. The frame being now drawn backwardly draws the can with itpositively, causing said can to roll through the runway and pressing itdown positively on the label.

Now, in order to allow the can-puller to get above, so as to fall downupon the can, I have the following construction: The ends of thecan-puller are provided with carryingrollers (Z4, which travel in thetrack-grooves a of the runway and hold said can-puller down. In thesides of the runway and above the trackgrooves a are the uppertrackgrooves a3. Near their rear ends these grooves communicate by aswitch-bar afl, which is pivoted at fr", so that it may swing. The lowerend of this switch-bar lies normally upon the `lower track-groove d',its point being iiush therewith, while its upper end extends beyond itspivot and rises above the level of the upper track-groove. At theirforward ends the two track grooves communicate by a groove a, the lowerfront edge of which is beveled, as shown. Now on the backward or inwardstroke of the frame the rollers l) of the said frame and the rollers dof the can-puller all travel in the lower grooves a', in which positionthe puller lies down upon and in contact with the can. \Vhen the back ofthe stroke is reached, said rollers simply raise the swingingswitch-bars a4 and pass under and beyond them; but upon the return orforward stroke the rollers d" of the can-puller 4iirst come `in contactwith the ends of the switch-bars and travel upon them, thereby swingingthe can-puller portion of the frame aB upwardly, so that its rollerspass into the upper track-groove. As they mount the inclines of theswitch-bars and pass beyond their pivotal center the weight of thecanpuller is sufficient to tilt the bars, whereby their lower ends areraised from the lower track-grooves, and the rollers l) of the frame Bat this moment reaching this point pass under the switch-bars andcontinue forwardly in the lower track-grooves, thereby carrying thepaste-roller back and forth constantly in the same plane; but thecan-puller portion is raised to a higher plane. lVhen it reaches theextreme forward end of the stroke, these rollers drop down through theconnectinggrooves ci, so that the can-puller comes down to its positionon top of the can. The vertical automatic adjustment of thefriction-roller of the can-puller provides for different diameters ofcans. The bevels of the connectinggrooves a avoid any tendency of therollers in passing them to stick or catch.

The mechanism by which the cans are fed one at a time is as follows:Under the forward end of the runway is mounted a rockshaft H, which hasextending forwardly and back from it the arms 7L, the ends of which aresuitably connected, as by a slot-and-pin connection at 7i', with thestop-plates twhich project at a forward inclination up through therunway. This rock-shaft has a crankarm h3, with which a long link or rodh" is connected, the forward end of which is provided with a long slotin which the lowerend of a swinging arm h5 freely plays, the upper endof said arm being forked and operated by an eccentric 7L on the end ofthe power-shaft E. New by operating said shaft the power is transmittedthrough the devices described to rock the shaft lvl under the forwardend of the runway and thereby to alternately project upwardly andWithdrawthe two plates h2. The outer one is projected to hold the seriesof cans back, while the inner one is withdrawn to allow the movement ofthe first can. Then when another can is to be fed the inner one israised, so as to stop the can temporarily, while the outer one islowered to allow it to come down to place. The object of inclining thestop-plates hi is to prevent the cans from moving out of place orslightly moving forward when the inner plate is withdrawn and before theouter one has been raised to hohl the row of cans back. Before the innerplate has left the edge of the can the outer plate will have reached thesurface of the can behind, so that it cannot roll. The connections shownare such that the plates move truly and their operation is effected onlynear the ends of the stroke.

Now, in order to center the cans as they roll into place to be engagedby the can-puller, I have the following device: In the sides of theguide-channel G, between the two stopplates h2, are thecentering-inclines g, which are pivoted to the sides, so that they maybe moved to and from each other. This movement is eected by a right andleft hand IOO IlO

lIO

threaded screw g', which engages them both. As the cans roll down thechannel they pass between the inclines g and are centered by them. Theadjustment of the inclines prevides for differentlengths of cans.

I is the label-box, consisting of a hollow casing extending downwardlydirectly under the runway of the machine, its top being on a leveltherewith. This box has a door I and is provided with avertically-movable false bottom ri, which carries the pile of labels.lts surface is preferably covered with felt or other material, such asrubber or cloth.

The labels are held up to position in the runway, so that thepaste-roller will pass over the topmost one of the series, by thefollowing means: The movable bottom ft' has a downwardly extending` stemi", which passes through the betteln of the label-box and carries uponits lower end a guide-pulley i2. Secured to the betteln of the label-boxat one end is a cord t3, which passes downwardly under the pulley 2 ofthe stem and up over a guide-pulley 4 under the box at its other end andcarries a weight NV, which is connected with it by a simplehook-connection, as shown, whereby said weight may be readily removedand replaced again when required, as when the labels have to be suppliedtothe box, and the movable bottom dropped down.

The effect of this weight is to exert a com stant upward tendency orstrain upon the stem, and consequently to keep the false bottom i withinthe label box pressed upwardly,

- so that the label pile shall always be in position to have thepaste-roller pass over the top most one. This strain or power beingconstant, the feed is automatic, and as each label is taken off by a canthe remainder of the pile is kept constantly held up to place. There isa peculiar advantage in this power device, which may be stated asfollows: Then the pile of labels is a large one, it has more weight thanwhen it is decreased to a smaller pile. Consequently7 at lirst sight itmight appear that if a weight sufcient to raise the entire or half pilewere employed then as the pile decreased in vweight the weight IV wouldbe too great and would exert an unequal and excessive upward power; but,en account of the arrangement of the string which suspends the weight,it will be seen that when the label pile is greatest, and consequentlythe stem of the movable bottom is pressed down, the string will assumean inclination nearer the vertical, and consequently the power of theweight will be greater in this position, so that it will be sufficientto hold up and keep raised the entire pile; but as the pile decreases inbulk and the movable bottom and stem rise the string approaches nearerthe horizontal, in which position the weight cannot act on it aseffectively, and thereby its power will be decreased, so that it willhold up the decreasing pile with a constant power. Thus even down to thelast label there will be the same constant power exerted to hold thepile up to the action of the paste-roller and can.

New in order to form a stop for the label pile, so as to hold it exactlyin the plane desired and yet relieve the topmest one as a can passesover it, I have the following locks or holders: J represents these locksor holders, and they consist of pieces of flat metal, preferably alittle yielding, so as to have a slight play as the paste-roller movesover them. They extend from each side of the runway into its interiorand lap over the top of the label pile. There are four or more of them,two being shown near each end, one at each side of the label pile. Theyare pivoted at j, so that they may swing from a horizontal plane, inwhich they overlap the labels, to a vertical plane, in which theyrelease said labels.

The tripping mechanism of the locks consists as follows: The locks orholders have upwardly-extending stems j', which engage sliding barsji,the rearend of which is acted upon bya springjfi, the tendency of whichis to hold the part-s forward, so that the locks or holders remain in ahorizontally-operative position. In the sides of the casing are pivotedthe triggerbarsj4, the ends of which project into the runway (t and intothe path of the sides of the can-puller. The ends of these trigger--barsare connected by links with the sliding barsj2, whereby the latter areforced backwardly against the power of their springs, thereby raisingthe locks er holders to a vertical position and releasing` the labels.It will be seen, therefore, that as the can-puller approaches the firstpair of trigger-bars its sides, coming` in contact with them, opera-teupon them in such a manner as to raise the first pair of locks orholders from the label pile, thereby freeing that end of the topmostlabel, so that the can following in the can-puller picks up that end ofthe label. As soon as the sides of the l puller release the trigger-barsthe locks or holders spring backto position over that end of the nextlabel. Then the sides ofthe canpuller come in contact with the next pairof trigger-bars and operate them so as to raise the locks or holders andrelease the other end of the first label, and the can following rolls itup upon itself. As soon as the puller has passed the second set oftrigger-bars the locks or holders thereof spring back to position andhold the next label. The under side of the locks or holders mayberoughened, if desired.

New, in order to held these locks or holders positively against anypossible displacement or the upward force of the label pile, I have thefollowing positive catch mechanism: There is one for each lock. Pivotedin the side of the runway is the catch-bar II, having a beveled innerend which projects into the path of travel of the sides of thecan-puller. It has a notched outer end or head lt', which lies normallybehind the vertical stem 7" of IOO IIO

- they come in contact with the inner ends of the catchbars, therebyturning them on their pivots, so as to release the stems of the locks orholders. Then the latter return to place, the heads of the catch-barsspring in behind their stems and hold them. The can-puller sides missall the trigger and catch bars returning, as the whole puller is thenelevated.

I may find it advisable to use a swinging or tilting platform to restthe label pile upon instead of placing it directly upon the false bottomt'. This platform is designated by i5,

y and it is pivotally connected at fi, at the middleof its sides, to thebottom t', so that it will tilt from end to end. The object of this isas follows: As has been described, the label pile is resisted and heldby four holders or locks, two being near each end of t-he pile, one oneach side. As the can rolls upon the label pile, the surface of which isslightly above the level of the runway, it presses the whole pile downaway from the locks, and as one pair of locks are withdrawn and theother pair do not bear on the pile, because it is pressed below theirlevel, there is a chance for the next label below the topmost one toslide out of place. This would be the tendency when using the movablebottom t', for the label pile would be depressed equally over its entiresurface; butby using the tilting platform only one end of the pile wouldbe depressed, while the other end would be raised into contact with theholders or locks, thereby preventing any displacement of succeedinglabels.

When using the tilting platform, its surface will be covered with feltor other material to enable the last label to be picked up readily bythe rolling can.

L is a vertically-movable guard-piece at the end of the label-box,extending all the way across, and which serves to hold the labels frombeing displaced endwise. This bar is held normally up by a spring Z andis adapted to be run down by the paste-roller and can as they pass overit.

In the runway, nearits rear end, is an opening in which plays a movabledischarge-platform M, which receives the can after it has picked upits'label. This platform is mounted upon the upper end of avertically-movable stem m, and is held normally in an elevated positionby means of a string m and suspended weight WV. The weight, however, isnot sufficient to counterbalance the weight of the can, so that when thecan rolls onto the Aplatform its weight is sufficient to carry it down,and it then rolls off into the dischargechute N. VThe weight W thenreturns the platform for the next can.

In order to supply the paste-roller with paste, I have the paste-'car O.This is'mounted upon the-tops of the runway sides, and is adapted to bereciprocated back and forth with the frame B by a suitable connectionbetween it and said frame. That connection is formed by adownwardly-extending arm o from the car passing into a simple socket 0on the guide-stein of the said frame. The paste-car is provided withsmall guide-wheels o`2 in front and with power-wheels o3 at the back.These power-wheels are upon the shaft or axle of a second feedpaste-roll P, which is in contact with the first feed paste-roll p,operating within the paste-car, and also in contact with-a thirdfeed-roll p', which lies in contact with the paste-roller of thetruckframe B. The rolls are to be covered with felt or any suitablematerial which will absorb paste. 'lhe second or middle paste-roll P iskept hugged up close to the first roll4 p by mounting its end boxes inelongated slots o4, so that they will slide, and controlling theirmovement and position by springs o5 upon adjusting-screws o, Rotation isimparted to these several parts by means of the rolling action of thewheels o3 on the feed-roll P. These wheels, in order to insure theirpositive rotation, are preferably provided with teeth, which engageextended racks o7 on the top of the runway sides. Thus the paste is keptconstantly supplied to the paste-roller and all the parts are kept inmotion, so that the paste is evenly distributed throughout the severalrollers. The third roll p of thepastecar has a flange p2 at each end toprevent the paste from running off the ends. The other roll plays insideof these flanges, and any paste getting onto its ends will be scrapedoif by said anges. To prevent the paste from dropping oif the ends ofthe rollers, said ends are made concave. The peripheries of thepaste-rolls are to be iliade with channels or grooves @c around themunder their felt or other coverings. The rolls carry more paste whenconstructed in this way. These chan nels or grooves may be opposite eachother or not and may be of any suitable number. rlhe feed-rollp is incontact with the pasteroller C and eifects its rotation, so as ,to receive the paste equally over its surface.

The general operation of the machine is as follows: The labels aresupplied to the labelbox through a door in one side thereof and areinserted in such numbers that the movable bottom on which they rest isdepressed to its lowest limit, and the top of lthe label pile is held inthe surface of the runway by the locks or holders. Paste is supplied tothe paste-car and cans are fed into the guide-channel G. The parts arethen set in motion, so that the puller drops over the first can, and asthe frame B recedes the paste-roller passes over the topmost one of thelabel pile, thereby supplying it with paste. The can-puller operates thelocks or holders, as heretofore described, to release successively theends of the topmost label and immediately lock the ends of the IOOunderlying pile. The can followin rolls over thelabels and picks up thetopinost one. This rolling is a positive one under the action of thecan-puller, the top roller of which insures the rotation oi' the can andits pressure upon the label from end to end, and also presses out.

thelabelsmooth as the can rolls it up. When the frame has reached thebackward limit of its stroke, the labeled can is received upon theplatform M and falls into the dischargechute. The frame now proceedsupon its return stroke, the can-puller rising to the highertrack-groove, as heretofore described, so as to reach an elevation fromwhich it can drop down onto the next can; but the paste-roller continuesat the same level and rolls over the labels again, so that it passestwice over the same label, once on each stroke. A further point ofnovelty lies in the provision of the ledges aT directly under thetrack-grooves a and upon which the lower edges of the canpuller sidesrest and slide. These form iirin bearings for the 'can-puller andprevent it from rocking or tilting, keeping itlevel. The trigger-barsjl1project into the runway just above these ledges, so that the sides ofthe can-puller must strike them.

IIaving thus described my invention, what I claim as new, and desire t-osecure by Letters Patent, is
